    electron-withdrawing groups are chlorinated in good to excellent yields (scalable to gram scale) using trichloroisocyanuric acid (TCCA) and catalytic Brilliant Green (BG). Visible-light activation of BG serves to amplify the electrophilic nature of TCCA, providing a mild alternative approach to acid-promoted chlorination of deactivated (hetero)aromatic substrates. The utility of the TCCA/BG system is demonstrated
    使用三氯异氰尿酸(TCCA)和催化艳绿(BG)以良好至极佳的收率(可缩放至克级)对含有吸电子基团的杂芳烃和芳烃进行氯化处理。BG的可见光活化可增强TCCA的亲电性质,为失活的(杂)芳族底物的酸促进氯化提供了温和的替代方法。通过与其他氯化试剂进行比较以及对包括咖啡因,利多卡因和非那酮在内的药物进行氯化,证明了TCCA / BG系统的实用性。

    A variety of arenes and heteroarenes are chlorinated in moderate to excellent yields using N-chlorosuccinimide (NCS) under visible-light activated conditions. A screening of known organic dye photocatalysts resulted in the identification of methylene green as the most efficient catalyst to use with NCS.
